No Idea How To Explain For The Title.

Question

So, I'm using my VideoWave that I got with roxio game capture HD pro. I've used it for a while, but it's really frustrating me now.

Sometimes, when I put videos into the timeline, I split the track, and after around 5 mins of no response, it does split and the new track has a big red (no entry) sign. From then on, it takes 10 mins of no response for the damned thing to work! I spent 4 hours last night trying to do something that should only take 30mins. So the question is, how do i get the video to work properly, whithout the (no entry) sign coming up?
